​Three officers fired a total of 18 gunshots at the suspect, striking him several times.

The off-duty detective who was gashed from his temple to his jaw when he tackled a man fleeing police with an 11-inch cleaver in a chaotic attack near Penn Station at the height of Thursday's evening rush left the hospital Friday afternoon. A small army of NYPD officers and union representatives, along with the father of detective Brian O'Donnell, cheered on the 16-year veteran officer as he was wheeled out of the lobby of Bellevue Hospital. O'Donnell, who appeared to be wearing a cast on his left arm and had an apparent cut running down his face waved to cops and doctors as he exited the hospital.
